I agree with you, the second option is correct. The data was first standardized according to the standards...

da·ta1

da·ta [dáytə, dáttə]
n (takes a singular or plural verb)
1. factual information: information, often in the form of facts or figures obtained from experiments or surveys, used as a basis for making calculations or drawing conclusions
2. computing information for computer processing: information, for example, numbers, text, images, and sounds, in a form that is suitable for storage in or processing by a computer


[Mid-17th century. From the plural of Latin datum , neuter past participle of dare “to give, grant” (source of English condone and vendor). The original English meaning was “accepted assumptions, premises.”]

Singular or plural?

Use of the term data has grown apace with the use of computer technology and of statistical methods. Because the word’s meaning is much like that of the singular noun information, and because its Latin -a plural announces the word’s plural status to us less plainly than a final s would, it is often treated as if it were singular. This use is extremely common, and few perceive it as wrong these days, especially given the word’s connotation of a collection or single unit made up of many informational subunits. All the same, in highly formal English, use of data as a singular is best avoided. According to the traditional view, Our data have been assembled over a number of years would be correct, and constructions such as very little data, the data shows…, and a great deal of data would be regarded as incorrect.
